New PSUs operate in challenging power conditions found in rugged operations

Technical Highlights:

Ranges between 30 W and 120 W outputs and 11.4 VDC to 50 VDC inputs

Can be used in a PC/104 stack; as a standalone unit in COM Express or custom SFFs

Operating range of -40°C to +85°C per MIL-STD-810G

Elma has added four new, rugged power supply modules to its growing family of power solutions. The PCI-104-based PSUs can be used as the bottom module in any PC/104, PC/104-Plus, PCI-104, PCIe/104 or PCI/104-Express embedded system stack arrangement. They can also provide power for other small form factor (SFF) embedded computing systems, such as COM Express.

The rugged mechanical PCI-104 form factor is designed to operate in demanding power conditions typically experienced in ground vehicles and aircraft applications. This enables the power supplies to function without active cooling in temperature ranges from -40°C to +85°C per MIL-STD-810G, when attached to a base enclosure for heat dissipation.

Each module withstands high levels of shock and vibration for defense ground vehicles (MIL-STD-810G) and military aircraft (MIL-STD-704F) for reliable operation in harsh environments.

Galvanically isolated, the DC/DC modules provide reliable signal isolation. The new PCI-104 power modules range from two outputs at 30 W up to five outputs at 120 W, combined (3.3 V, 5 V, ±12 V), and support 11.4-50 VDC input ranges for 28 VDC applications.

The power supplies are compatible with a host of embedded CPU modules on the market. For example, Elma integrates them into various mission-critical sub-system assemblies, such as its NetSys family of rugged Cisco Embedded Services Router (ESR) computers and the ComSys family of communications platforms.

With one of the widest product ranges available in the embedded industry, Elma also offers standard and custom cabinets and enclosures as well as precision components such as rotary switches/encoders, LEDs, front panels and small cases.

Elma Electronic manages entire projects from initial system architecture to specification, design, manufacturing and test through its worldwide production facilities and sales offices. The company serves the mil/aero, industrial, research, telecom, medical and commercial markets and is certified to ISO 9001 and AS 9100.

With U.S. headquarters in Fremont, Calif., the company maintains multiple sales, engineering and manufacturing operations in Atlanta, Ga., and Philadelphia, Pa.

2018 is a new year for RF Front-End Module suppliers, and a turning point for some smartphone-making original equipment manufacturers (OEMs). In 2017, we saw an important choice in adopting Power Amplifier Module integrated Duplexers (PAMiDs) that distinguished high-end and mid-range smartphones....
